Donna Martin Graduates! Beverly Hills, 90210 Stars Then and Now

Tori Spelling, who celebrated her 41st birthday Friday, has made headlines recently for documenting her marital troubles on the Lifetime reality series True Tori.

But the actress’s most iconic small-screen moment occurred 21 years ago this week: On the Beverly Hills, 90210 episode “Something in the Air,” the West Beverly gang memorably protested the school’s decision to suspend Spelling’s character after she got drunk at prom, chanting the epic battle cry “Donna Martin graduates!”

With a little help from Photoshop, we’re letting West Beverly’s class of ’93 reunite with their younger selves to reminisce about the Peach Pit days.

Garth could tell her younger self about her funniest encounter with a 90210 fan. “There are people who are experts, but this guy was crazy,” she told PEOPLE in February. “He knew everything and he would not stop talking about it.”

“I felt that the character of Brandon had kind of run his course. I had explored everything I wanted to explore with him,” Priestley, who departed the show during its ninth season, told CNN earlier this week while promoting his new memoir. “In retrospect, I do regret leaving,” he admitted.
